What's the best way to ground myself when my PSU is unplugged?
Asked by

I'm building a PC and I've read that it's a good idea to use the power supply unit (PSU) while it's plugged in but switched off for grounding. However, I've also heard that I shouldn't have it plugged in when upgrading components. Is this true? I already have a wired anti-static wristband, but where should I attach the alligator clips to ground myself properly? Can I insert a piece of metal into the third hole of the socket and connect to that? Or is it fine to connect it to the end of my laptop charger?

If you're using a wrist strip, attach it to a metal part of your case for grounding. Modern components are pretty resilient to static, so the risk of frying them is minimal if you're careful. Just avoid standing on carpet when working.

You're absolutely right; always unplug the PSU before you plug or unplug anything. Touching the case can help with grounding, and pressing the power button before you start helps drain any leftover power.

You'll want to connect your wrist strap to the metal case of your PC. Don't worry about having the PSU plugged in; it’s fine as long as you're grounded properly. Just make sure you're not on a carpet, which can increase static.

You can turn off your PSU, unplug it, and then press the power button for about 3-5 seconds to discharge any residual electricity. Then, just touch a metal part of your case, and you should be good to go!
